Ethereum’s Pectra Upgrade: A Deep Dive into the Latest Developments
By Extreme Investor Network Team
Published on January 25, 2025
In a pivotal moment for the Ethereum network, core developers gathered on January 23, 2025, for the All Core Developers Consensus (ACDC) call #149. Chaired by Ethereum Foundation Researcher Alex Stokes, the meeting addressed pressing concerns surrounding the Pectra upgrade, specifically focusing on bugs that have emerged on the Pectra Devnet 5. With plans aiming for a mainnet activation on March 11, 2025, the developer community is eager to achieve a seamless transition amidst the challenges.
Understanding the Challenges: Pectra Devnet 5 & 6
During the ACDC call, developers tackled a critical gas estimation issue that resulted in a rare three-way chain split on Pectra Devnet 5, as highlighted by EF DevOps Engineer Rafael Matias. This problem has delayed the network’s finalization, prompting various client teams—including Nethermind, Reth, Erigon, and Besu—to collaborate on immediate fixes. The recent hive test conducted on Devnet 5 unfortunately did not yield successful results, signaling a pressing need for further investigation.
In light of these challenges, the community is rallying to roll out Devnet 6 prior to the upgrades of public testnets. Matias emphasized the necessity of implementing effective bug fixes and executing successful hive tests before moving forward. Developers also discussed notable changes to EIP 7702 on GitHub, with Geth developer known as ‘Lightclient’ assigned to finalize the necessary adjustments. While a new version of the Pectra CL specifications (1.5.0-beta.1) was introduced, it remains largely unchanged from prior releases.
The Road Ahead: Public Testnets and Mainnet Fork Timing
In a proactive step, the developers proposed a timeline for the public testnets and mainnet upgrades. EF Protocol Support Lead Tim Beiko set a tentative date for mainnet activation on March 11, 2025, marginally less than a year post-Dencun upgrade. This proposed schedule mandates upgrades for the public testnets, Sepolia and Holesky, by February 19 and February 24, respectively—preferably ahead of these deadlines to ensure seamless preparation.
While this timeline outlines ambitious progress, developers have yet to rectify the existing bugs in Devnet 5 or initiate Devnet 6. Beiko is expected to present specific block numbers for further discussion in the next ACD call, underscoring the urgency for near-final client releases by February 3, 2025.
Major Developments: PeerDAS
One of the standout initiatives discussed was PeerDAS, a significant scaling improvement anticipated in the Fusaka upgrade following Pectra. This upgrade aims to enhance Ethereum’s capacity to process blob transactions, potentially increasing throughput by an impressive factor of eight, according to EF Research Analyst Ansgar Dietrichs. However, developer Terence Tsao from Prysm indicated that scaling blob throughput presents its own set of challenges, necessitating further research and testing before its implementation.
Enhancing Governance: Fusaka Fork Planning Process
Amidst these technical discussions, Beiko called for constructive feedback on the Ethereum fork planning process. Acknowledging the coordination hurdles faced during Pectra’s rollout, he proposed the establishment of an Ethereum Magicians forum, designed to foster dialogue around governance improvements for future upgrades and to encourage enhanced community participation.
As we stand on the brink of these transformative developments, it’s crucial for stakeholders and community members to stay engaged and informed. Stokes reminded client teams of the upcoming Pectra testing calls, with less than 100 days remaining to remove the pre-Merge history from Ethereum clients.
